  1. A: about 3,000. It stretches for about 1,429 miles off the coast of Queensland, Australia. Source: NOAA Ocean Service
  2. C: wind shear. Wind shear helps set up the spinning air inside storms that can form tornadoes. Source: NOAA NESDIS (SciJinks)
  3. B: copper. The protein is called haemocyanin; human blood uses iron-based haemoglobin. Source: Natural History Museum, London
  4. A: 74 miles per hour. At 39 miles per hour, a storm is first called a tropical storm. Source: NOAA NESDIS (SciJinks)
  5. B: new moon and full moon. The name comes from the tide 'springing forth,' not from the season. Source: NOAA Ocean Service
  6. B: Prochlorococcus. Most of the ocean's oxygen comes from drifting plankton like this. Source: NOAA Ocean Service
  7. C: the Challenger Deep. It lies at the southern end of the Mariana Trench in the western Pacific. Source: NOAA Ocean Service
  8. C: about 3,682 meters. That is about 12,080 feet, more than two miles down. Source: NOAA Ocean Service
  9. A: the temperature of the eggs. Scientists call this temperature-dependent sex determination, or TSD. Source: NOAA Ocean Service
  10. B: calcium carbonate. Most stony coral polyps are only one to three millimeters across. Source: NOAA Ocean Service

Make a different round

1. Who’s playing?
2. Tick up to three themes

Three themes give three questions each and a riddle to end on. One theme gives all ten. If you tick more than three, the first three count.

How the round maker works

  • Little is for ages 6 to 8 (kindergarten to 2nd grade), Middle for 9 to 11 (grades 3 to 5), Big for 12 and up. A round never mixes ages; at a mixed table, play one round per age on the same themes.
  • Three themes give three questions each and a riddle to end on. Two give five each, and one gives all ten. Shuffle keeps the age and the themes and draws ten new questions.
  • Every question about animals, the ocean, dinosaurs, space, planet Earth, weather, plants, the body and Thanksgiving was written by Peabody and checked against one page from NASA, NOAA, USGS, the Park Service, the USDA, the National Archives, the Smithsonian or another public source, named under its answer. Capitals come from each state’s USA.gov page, word meanings from Peabody’s word bank, and sums are worked out on the key.
  • The round’s address is the round, so you can send it, print it or play it again. Scores stay on this device. There is nothing to sign up for and nothing anyone types.
